specific Embodiment approach

[0041] A flexible connection device between a thin-walled cast-in-place concrete enclosure structure and a steel structure, comprising a first steel structure 1a and a first water-stop steel plate 2a, characterized in that:

[0042] The first water-stop steel plate 2a and the second water-stop steel plate 2b are welded on the first steel structure 1a, and are arranged along the span direction of the first steel structure 1a; on the second steel structure 1b, two rows are welded in the same way as the first steel structure 1a The water-stop steel plate is symmetrical to the first steel structure 1a, and the connection between the water-stop steel plate and the steel structure or the water-stop steel plate is fully welded;

[0043] The waterproof rock wool board 5 is respectively pasted inside the first water-stop steel plate 1a and the second water-stop steel plate 1b through the adhesive glue 4, and pasted outside the first water-stop steel plate 1a and the second water-stop st...

Abstract

The invention discloses a thin-wall cast-in-situ concrete enclosure structure and steel structure flexible connection and water stop treatment method, which comprises the following steps of: A, performing surface treatment on a steel structure; B, welding a water stop steel plate; C, manufacturing a waterproof rock wool plate; D, installing the waterproof rock wool plate; E, welding horizontal and vertical steel bars; and F, closing concrete. By the method, the crack spreading of a concrete enclosure structure is effectively controlled, the condition that the concrete enclosure structure is deformed and cracked and then leaked because the concrete enclosure structure and the steel structure have a large linear expansion coefficient difference due to temperature change is avoided by utilizing flexible connection and the water stop steel plate on the surface of the steel surface in a projection area of a cast-in-situ concrete enclosure structure arranged at a joint, and the problem thata flexible connection material is non-fireproof in the welding process is solved by adopting the waterproof rock wool plate which is a non-combustible material. In addition, the method is simple in construction, and safe and feasible, the contraction crack of the concrete enclosure structure can be effectively controlled, a seepage path is blocked, the crack resistance and seepage resistance of the joint are improved, and the service life of the concrete enclosure structure is greatly prolonged.

Description

technical field [0001] The invention relates to a building construction method, and more specifically relates to a thin-wall cast-in-place concrete enclosure structure and a steel structure flexible connection and water-stop treatment method. The utility model has the advantages of preventing cracks caused by the inability of the concrete enclosure structure to freely deform, and preventing water from combining different materials. Background technique [0002] At present, a multi-layer composite structure enclosure structure using thin-walled cast-in-place concrete walls is gradually applied to various steel structure buildings with novel and unique spatial shapes. , sound insulation, waterproof and moisture-proof, fire-resistant and durable and other functional requirements, and can complete various complex space shapes along with the main steel structure boundary. Although the combined structure form takes advantage of the respective material properties of concrete and...
